Problem with DHCP

[N3ste]

Hi, I would like to ask what the problem is. When I have a router and a computer connected and a DHCP server is set up, the computer automatically requests an ip address and assigns it, but when I put a switch between them, I get "DHCP failed. APIPA is being used." Thank you in advance for your reply.

Hi

Show us the configuration of the router and the two interfaces on the switch, and we will take a look at it.
